An Inventory of Vehicles Traversing the 
Lower Roadway at O'Hare International Airport 

Ed Christopher, Associate Project Engineer 



ABSTRACT 

This report summarizes traffic classification counts taken on the lower 
roadway at O'Hare International Airport. The lower roadway serves passengers 
departing the airport. The counts were taken for a fifteen hour period on 
Tuesday, June 25, 1985 and again on Friday, August 23, 1985. Of particular 
interest is the mix of taxi, livery, courtesy vehicle, bus and private auto 
traffic utilizing the airport on the surveyed days.

Int roduction 

In July 1985 the City of Chicago, Department of Aviation established the 
O'Hare Traffic Management Task Force. The aim of the task force is to take 
action towards alleviating roadway and parking congestion at O'Hare 
International Airport. In an attempt to assist the task force, CATS staff, at 
the direction of the Private Providers Steering Committee conducted counts of 
all vehicles traversing the lower roadway at O'Hare. The lower roadway is 
used for trips departing the airport. These counts were conducted as a 
follow-up to similiar counts taken in May 1984 and presented in (I). The 
counts presented in this report were taken on two different days: Tuesday, 
June 25, 1985 and Friday, August 23, 1985. The time frame for the counts was 
between 7:00 AM and 10:00 PM except where noted. All types of vehicles 
departing the lower roadway at O'Hare on these two dates were counted. 

Co unt Location 

For both days the counts were recorded and tabulated each hour at two 
separate locations on the lower roadway. Figure 1 shows the count locations. 
Both locations were on the lower roadway before its merger with the upper 
roadway. O' Hare's two level roadway system is designed to segregate departing 
and arriving air passenger ground traffic. Departing air passengers are 
directed to the upper roadway while arriving air passengers are directed to 
the lower roadway. The lower roadway is used primarily for those vehicles 
serving passengers departing the airport although this roadway also carries a 
significant number of vehicles circling the terminal area. 

The need for two different count locations arose from the temporary 
placement of the International Terminal (Terminal 4) in the lower level of the 

parking garage. The primary purpose of these counts was to identify

the traffic volumes of vehicles serving arriving air passengers. Since the 
new international terminal roadway serves both arriving and departing air 
passengers it was necessary to conduct separate counts of the vehicles 
departing the international roadway. 

Commercial Vehicle Classification 

Separate tallies were kept for ten classifications of vehicles including: 

1. Chicago Taxicabs 6. Courtesy Vehicles 

2. Suburban Taxicabs 7. Rent-A-Car Shuttles 

3. Chicago Limousines 8. Airport Shuttles 

4. Suburban Limousines 9. Commercial Buses 

5. Passenger Cars 10. All Other Vehicles 

In addition to the number of vehicles the passengers per vehicle were 
recorded for the first four vehicle types during both the June and August 
counts. Vehicle occupancy was also recorded for passenger cars during the 
August counts. However, the passengers per vehicle were not recorded for 
passenger cars during the June counts. 

The following sections provide a brief explanation of each of the vehicle 
classifications. 
Chicago Taxicabs. 

These vehicles were identified by their license plates, medallions and 
the number painted on the cars. For Chicago taxicabs the number on the 
license plate always corresponds to the number painted on the vehicle. 
Chicago taxicabs also carry a 4 inch square metal tag (medallion) bolted 
to the right side of the hood. Only Chicago taxicabs have medallions. 



-3- 



Suburban Taxicabs. 

It was assumed that all vehicles with taxicab license plates not carrying 
a medallion or other Chicago marking were suburban taxicabs. 

Chicago Limousines. 

These vehicles were identified by their license plates. Besides having a 
special livery license plate, all Chicago licensed limousines have the 
number "7" at the beginning of their license plate number. 

Suburban Limousines. 

All other limousines displaying a livery license plate not starting with 
the number "7" were assumed to be suburban limousines. 

Passenger cars. 

This classification included all private vehicles, cars, station wagons, 
passenger vans and pick-up trucks having an Illinois passenger car 
license plate. 

Courtesy Vehicles. . 

Vehicles in this class include the hotel and motel shuttle vehicles. 
These vehicles range from small buses and vans to station wagons and 
passenger cars. These vehicles were identified by their markings which 
indicate the hotel or service organization sponsoring the vehicle. 

Rent-A-Car Shuttles. 

This group includes those vehicles owned and/or operated by car rental 
companies which provide a shuttle service for their clients to/from the 
terminals and the rent-a-car locations. Both on and off field rent-a-car 
shuttles were counted in this group. Typically the vehicles are small 
buses with the name of the company painted on the side. As with the 

courtesy vehicles this group included small buses, vans, station wagons 
and passenger cars. 



4- 



Airport Shuttles. 

Counted here were vehicles providing free shuttle services around the 
airport property and which were clearly marked "free airport shuttle.'' 
These include employee shuttles, terminal shuttles, and the shuttle buses 
serving the remote parking lots. 

Commercial Buses. 

This category includes all the for-hire buses operating to/from o'Hare. 
Examples of buses in this group are CTA, RTA. Greyhound, Continental, 
Tri-State, and those buses providing regional services. Buses operating 
as charters are also included in this group. 

Other Vehicles. 

This group consists of tow-trucks, police and fire vehicles, construction 
vehicles, motorcycles, military and any other vehicle not falling into 
one of the above categories. 

H ourly Counts 

Summaries of the vehicles counted on Tuesday, June 25, 1985 are provided 
in Appendix A, Tables Al thru A12. Summaries of the counts taken Friday, 
August 23, 1985 are presented in Appendix B, Tables Bl Thru B14. 

These counts represent the best available data on the mix of vehicles 
serving the airport. The Tuesday date was chosen as representative of a 
typical weekday. On the other hand, the Friday date is more accurately 
characterized as a peak weekend day. However, it should be noted that since 
this data represents only two data points it is difficult to develop valid 
comparisons between the two days. Therefore, this paper will presents only a 

profile of the vehicles serving the airport on the days studied. The number 



-5- 



and share of vehicles in each category on the two count days is presented in 
Table 1. 

As Table 1 shows there were significantly more autos observed on the 
lower roadway on Friday, August 23, 1985 than were observed on Tuesday, June 
25. Given the fact that 56% of these autos contained only a driver a possible 
explanation for the increased traffic is that more of these vehicles were 
circulating around the airport while waiting for their passengers to arrive. 
Unfortunately auto occupancy for the June counts was not measured. Nor were 
vehicle occupancies measured for the hotel/motel, rent-a-car, airport shuttle, 
commercial bus and other categories. 

Table 2 presents the number of vehicles traversing the lower roadway 
which were carrying passengers on each of the survey dates. That is, the 
driver only taxis and limousines and the August 23 driver only autos have been 
excluded from Table 2. This should present a slightly truer picture of the 
mix of vehicles actually departing the lower roadway. It should be noted, 
however, that reducing the number of autos for the Friday counts by the number 
of driver only vehicles while not performing the same adjustment on the 
Tuesday data will affect the mix of vehicles being shown. 

Further, the City of Chicago changed some of the operating procedures at 
the airport between the two count dates which could affect the vehicle mix 
observed there. Foremost among these changes was the addition of more police 
whose primary purpose was to keep traffic, especially the passenger cars, 
moving. It is likely that this increased enforcement resulted in a greater 
number of passenger cars circulating the lower level than there were before 
the additional police were added. Whereas in June the private auto driver 

might prefer to park or stand illegally at the curb, in August this driver

would be more likely to recieve a ticket or tow by doing so and therefore more 
likely to circulate as he/she waited to pick-up passengers. 

Based upon the above data the following mix of vehicles can be expected 
on the lower roadway:: 

Chicago Limousines 1% - 2% Courtesy Vehicles 3% - 8% 
Chicago Taxlcabs 13% - 20% RentA Car Shuttles 7% - 10% 
Suburban Limousines 10% - 15% Airport Shuttles 1% - 3% 
Suburban Taxicabs 3% - 4% Commercial Ruses 2% - 3% 
Passenger Cars 37% - 56% Other Vehicles 3% - 5% 

Other Observations 

1. The number of vehicles traversing the lower roadway remained relatively 
the same for both days with the exception of passenger cars. This could 
indicate that the ground transport choice of the regular or business 
traveler is relatively constant. The June data represents a normal 
business day. The August data undoubtedly is inflated by a larger number 
of vacation or recreational travelers. 

2. The vehicle types showing the greatest changes were: 1) passenger cars, 
2) Chicago taxicabs, suburban limousines, and, to a lesser extent, 
courtesy vehicles and the rent-a-car and airport shuttles. 

3. Empty circulating vehicles still represent a significant share of the 
lower roadway traffic at O'Hare as shown in Table 3. 

4. Both Chicago and suburban limousines carry more passengers per vehicle 
than the overall average occupancy as indicated in Table 4. This may be 
explained by the tendency to multiple load among these carriers as 

compared with the other operators at the airport.
